Notes: This a rare species, even more fertile, I saw for the first time. It and was growing in a vertical exposed rock. According to 1: “Very similar to D. atlantica (see observation 72617) and to D. plumbea (see observation 77492) but with numerous elongate schizidia (flattened to spoon-shaped isidia). Schizidia often blackened at tips. Apothecia are very rare, the discs brown to black. Part of Macaronesian element in British and Irish lichen flora”. I made the microscopy to observe the spores but the photos are quite bad. Even so I could confirm their similarity wih those of D. plumbea, being hialine, fusiform and with appproximate dimensions of 15 × 6 µm. It fits very well the descriptions given in the references.
